HM830 RC Paper-Airplane support?

I have no idea, but I ordered one.

I got my paper-airplane controller today. The controller is an nrf24L01 (or compatible). I've got traces for the functions, so putting together a protocol likely won't be difficult. The only hiccup is that I haven't actually worred with the NRF24L01 much.

Does anyone know what the right-button or A/B/C buttons do? The A/B/C is documented as 'LED Changing Button' But it doesn't seem to do anything as far as I can tell.

the left shoulder button (accelerate) sends a command that is different than full-throttle. I don't know how the Rx responds to it, but in theory accelerate + full throttle may give an extra kick.
The right-shoulder button does send a command to the Rx. I don't know what it does (if anything)
The ABC button also sends a command to the Rx (similar though not identical to the right shoulder button)

The trim is completely independent of the rudder control.

The protocol is pretty straight forward, using no encryption and just a CRC8 checksum. The channel-hopping table seems fixed, but the pairing-ID may be Tx specific. If so, it seems pretty simple to handle.

I have implemented the protocol, and all that remains is to test and debug, but that'll need to wait until tomorrow.

Ok. I've uploaded a nightly build that supports the HM830. All capabilities should be functional.

I also created an initial model file here:

That will likely need some more work to improve though.

The protocol only has 4 bits for rudder (even through it has 6 bits for rudder-trim, these seem to control the left vs right prop ratio, and do not act the same as rudder
The throttle has a value of 0-100 which is ~6.5 bits
I mapped the Accelerator (left-shoulder) to channel 3 and the right-shoulder (unknown function) to channel 5
